DEVICE FOR APPLYING PASTE TO LABELS.

Application filed November 24, 1923.

My invention relates to a device for applying paste to labels such as is described inl United States Patent No. l 395,056 issued October 25th, 1921, to Arthur F. Nelson and in Which a plurality of spaced paste applying discs are mounted on a shaft. the labels being carried through the device and pressed into engagement with the peripheries of said discs by a plurality of pressure applying discs Which are mounted on a countershaft operatively connected With the first-mentioned shaft.

The primary object of my invention is the provision of an improved device of the type referred to which will be of very simple construction, inexpensive to manufacture, easy to keep in a clean and sanitary condition, and strong and durable in serv ice.

A further object of my invention is the provision of means integrally formed with the paste applying discs for maintaining said discs in spaced relation and preferably also for holding them against angular movement relative to eachother, thereby reducing the cost of making the discs to a minimum and also facilitating the assembling of the discs on their shaft.

Another object of my invention is the provision of improved means for locking or clamping the paste applying discson their shaft.

Still another object of my invention is the provision of a shaft having a plurality of spaced, transverse grooves in combination 'with pairs of slotted discs so formed that they will be self-locking when forced into co-operative relationship in the respective grooves on said shaft,

It is another object of invention to provide improved means for mounting the respective shafts in the device and so arranged that they may be readily removed from or replaced in the device.

In machines of the type referred to, the

labels enter through one slot. pass between the paste applying` and pressure discs and pass out through. another slot; and, it is a further object of my invention to provide improved means to prevent the labels from following the paste applying discs and to guide them through the outlet slot.

In connection with labels for certain purposes, it has been found desirable to apply a thin film of paste to substantially the Serial No. 676.674.

entire under surface of the label; and, it is a further object of my invention to provide a roller for applyine'the paste to the labels in combination with the pressure applying discs and a scraper to remove the excess paste from the roller, the scraper preferably oeing arranged so that it has spaced portions Which bear directly on and remove the paste from those portions of the roller which are engaged by the respective pressure discs and thus prevent the pasteV from collecting on the pressure applying discs.

The invention consists in the novel constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above-stated objects and such other objects as Will appearfrom the following description of a certain preferred embodiment, illustrated in the accompanying drawings, wherein- Fig. l is a longitudinal sectional View of a device embodying certain principles of my invention;

Fig. 7 is a perspective view of the means for stripping the labels fromthe paste applying means shown in Figs. 5 and 6; and

Fig. 8 is a perspective view of a fragmentary portion of the scraper for removing excess paste from the paste applying means shown in Figs. 5 and 6.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1` to 4:, inclusive, the mechanism of the device is housed Within a suitable casing preferably comprising a base member l0 and a cover member 11. A paste receptacle 12 is provided in the base member. rIhis receptacle is made a little shorter than the base by providing` a transverse Wall or partition 13 so as to provide room for the driving mechanism hereinafter described. The cover member is provided with a plurality of depending lugs 11 which engage the base member and prevent it from shift-ing laterally thereon. The and cover members are preferably cast from any suitable metal.

The cover member is provided with bearings 15 and 16. One end of a shaft 17 is journaled in the bearing 15. v@ne end of a crank handle member 18 projects through the bearing 16 and has threaded engagement with the other end of the shaft 17. The paste applying discs 19 are formed With a central aperture 20 and, excepting the end disc 19a, have a plurality of tongues 21 stamped therefrom and a. similar number of recesses 22 formed therein, the tongues and recesses of the discs beingso arranged that, when the discs are assembled on the shaft 17, the extremities of the tongues of one disc Will fit into the respective recesses of one of the adjacent discs. by which arrangement the discs are maintained in spaced relation. and are Vheld against relative angular movement. The shaft 17 is preferably provided, adjacent its respective ends, with circumferentially extending` grooves into each of which a slotted locking member or disc 24 may be forced. rEhe grooves 23 are so located that the discs 19 must all be as sembled in proper relation on the shaft 17 and forced closely together in order to force the members 24 into their respective grooves. The shaft 17 carries a gear 25 which meshes with a gear 26 mounted on a countershaft 27.

The cover member 11 is also provided with bearings 28 and 29. One end of the shaft 27 is journaled in the bearing 28. screw 30 extends through the bearing 29 and has threaded engagement With the other end of the shaft 27. The shaft 27 is provided vvith a plurality of spaced circumferentially extending grooves 31, a plurality of pairs of pressure applying discs being forced into said respective grooves. One of the dises 32 is shown in Fig. 1. 1t will be noted that the disc is provided With a slot 33 and that it is also punched to provide depressions 34. When the discs 32 are mounted on the shaft 27 one disc of each pair is slipped into the groove in the shaft from one side and ythe other disc of that pair is slipped into said groove from the other side, the depressions 8st of one disc snapping into the depressions of the other disc. thus locking the two discs on the shaft and holding them against relative movement. The 4discs 211 and B2 are preferably formed from the same. die.

The disc-s 19 and 32 are of such diameters as to cause their periplieries to pass substantially through a common plane when the discs are mounted in the manner described. The discs 32 are mounted on the shaft so that they operate substantially midway between certain of the discs 19 which prevents any paste on the discs 19 from being transferred to the discs 32. The discs 19 and 32 may be stamped out of any suit-able metal. substantially like the discs 19 may be mounted on the shaft 27, if desired, also that discs like the discs 32 may be mounted on the shaft- 17 for applying the paste to the labels. The arrangement shown in the drawings is preferred, however, because the larger discs are less likely to Yabble when they are provided with the tongues 21 and recesses 22 and are firmly held on the shaft.

The cover member on one side is provided with a longitudinal slot through which the labels are inserted or fed into the device and on the other side with a longitud inal slot 3G through Which the labels pass they leave the device. As the labels are fed throughL the device between the discs 19 and 32. the discs 32 press the labels into engagement ivith the peripheries of thediscs 19, the labels being slightly corrugated as they pass through betiveen the tivo sets of discs. llihen the shaft 17 is rotated, the discs 19 turn vvith it, the peripheries of these discs passing through the body of paste. certain amount of paste will adhere to the peripheries of these discs and will be carried thereon and transferred to the labels as lthey are fed through the device.

ln order to `j'irevent the labels from adhering to the discs 19 and to insure their passing through the slot 3G, I preferably provide a plurality of lingers 87. rlhe cover member adjacent the slots l5 and 536 is provided with a plurality of recesses or aj'iertures 3S. As shoivn in Fig. 1, the fingers 37 lie betiveen certain of the discs 19 and the extremities of said respective fingers are bent around substantially at right angles so that they may be inserted into the recesses or apertures 38. l.Vhen the lingers are arranged in the manner described, they are independent of the shaft 17 and they do not interfere in any Way with the removal or replacing of said shaft and the discs assembled thereon. The labels may, if desired. be fed through the device from either side. Any paste Which may flow down the respective sides of the cover member will pass back into the paste receptacle through the longitudinal slots 39.

The operating mechanism being mounted in the cover member. may be 'removed ivith the cover as a unit. The paste receptacle may then be easily cleaned and refilled. rhe cover member with the operating mechanism may be positioned over a basin of hot Water so that the paste carrying discs project thereinto and the crank `given a feu' turns. which usually results in 'freeing tht discs of all paste. However. if paste still adheres to these discs, the discs may be reltwill be obvious that dises formed rec moved with the shaft 17 by unscrewing the crank 18. The shaft 17 and the discs 19 mounted thereon may then be placed in Water and the accummulated paste soaked ofi.

In the embodiment illustrated in Figs. 5 to 8, inclusive, the paste applying means is in the form of a tubular roller 40 closed at its respective ends by heads 41 soldered or otherwise fixed to the shaft 42. The shaft 42 may be mounted in the base member in the same manner as the shaft 17. In this embodiment a scraper 43 is mounted on one side of the cover member 11, the scraper projecting through the slot The scraper is positioned so that the spaced portions 48 thereof bear directly on the roller 40, that part of the scraper between the portions 48CL being close to but not bearing on the roller. A member 44 is fixed to the other side of the cover member 11 and is formed with a plurality of fingers 45 which project through the slot 36, the extremities of said fingers bearing on the roller 40. The portions 43a of the scraper and the fingers 45 are so located that they are in alignment with the pressure applying discs 32. The portions 43EL scrape those portions of the roller which are directly underneath the respective discs 32 and are engaged by the respective fingers 45, and, therefore, the transference of any paste to the discs 32 and the fingers is prevented.

lI do not intend to limit the invention to the details of construction shown and described, except only in so far as certain of the appended claims are specifically so limited, as it will be obvious that modifications may be made Wit-hout departing from the principles of the invention.
